* This class allows users to insert a chain of characters and show all the sentences of the JComboBox that match its first ones characters with it. |
|
| 66 | 65 |
* This class is also a Java Bean. |
| 67 | 66 |
* The behavior of this componet can be configurated by 6 flags: |
| 68 | 67 |
* + The appearence of the items showed at the beginning and when the user presses the ESCAPE key: (This is configured with 2 flags -> 3 different states are possible) |
| ... | ... | |
| 76 | 75 |
* + Key Sensitive or not when the user writes |
| 77 | 76 |
* -> key_Sensitive -> When we write on the TextField it can discriminate upper cases from down cases (if true) or not (if false) (This is configured with 1 flag -> 2 different states are possible) |
| 78 | 77 |
* + Use one color (black) or 2 colors (black by default and red if the string written doesn't match with the beginning of all items) |
| 79 |
* -> only_One_Color -> The text on the textField only will be showed on black color (if true); false -> if the text on the textField doesn't match with any current item of this component -> the text
|
|
| 78 |
* -> only_One_Color -> The text on the textField only will be showed on black color (if true); false -> if the text on the textField doesn't match with any current item of this component -> the text |
|

* will be showed on red color |
